• 1) make sure your computer isnt overheating this will cause lag spikes, mabye open your compuer and look if there any dust and stuff that might cause the problem, or check if your fans are malfunctioning.
  
  2) make sure your cpu isnt going on 100%, if so close any unnecessary programs running in the background.
  
  3) make sure to have atleast 10gb of storage in the drive u installed osu on.
  
  4) disable any overlays like Steam, Discord or anyother FPS overlay program.
  
  5) make sure your drivers are up to date by updating to the newest versions.
  
  6) run on unlimited fps, this will lower your ms 'only run unlimited fps if your computer can support it'
  
  7) close any web browsers, or server apps (including file sharing/torrents). Close all other background programs and tray icons and see if the problem persists.

if none of the things above helped try to run your osu in compatibility mode, this can fix some issues but if not just leave it off
